  • Carl Marrs

    Single Pitch
    Climbing School Instructor, Guide

    Emergency Medical TechnicianAmerican Mountain Guide AssociationCarl is a native to the PNW and has been exploring it since the first time his parents let him out the back door. Tree climbing as an elementary school kid progressed to rock climbing as a teenager, which developed into teaching and sharing climbing as a young adult. His career trajectory has involved instructing climbing since 2012. Taking every opportunity to go climbing and share it with others - whether at crags, on alpine granite, or glaciers - is what fulfills him.

    A jack of all trades, Carl is equally comfortable clipping bolts, slapping boulders, placing cams, slogging up glaciers on foot or skis, and questing on alpine rock. He is overjoyed for the opportunity to be a steward and help others in their progression through climbing of all types.

Lyra has guided expeditions to several of the Seven Summits, including Denali, Mount Elbrus, and Aconcagua, as well as steep rock climbs in Yosemite Valley, alpine routes in the North Cascades, long rock climbs in the desert southwest, and athletic ascents in the High Sierra.

    In addition to guiding, Lyra has applied her skill set to industry and education. She has worked in technical field support for scientists in Antarctica, and as a member of the Joint Antarctic Search and Rescue Team. She has worked as an Adjunct Instructor for the University of Alaska, Fairbanks, teaching mountaineering skills to high school girls as part of the Inspiring Girls Expeditions program, a non-profit field science education program.

    On rest days, Lyra works as a freelance writer and Review Editor for OutdoorGearLab.
